靜電紡絲法製備陶瓷奈米螢光纖維探討表面形貌與應用

本研究主要是利用靜電紡絲法製備奈米級陶瓷纖維，在前驅體溶液配製中，加入適量的PVP和溶劑使濃度適當，並成功製備出大量奈米纖維；且經過高溫熱處理過後，纖維不易斷裂破碎，利用下列儀器FE-SEM、AFM、HRTEM、XRD與PL進行分析。第一部份：利用不同高溫熱處理溫度製備陶瓷奈米螢光纖維，發現高溫熱處理溫度越高陶瓷奈米纖維中的結晶越大越緊密排列。第二部分：著重於靜電紡絲形貌纖維的控制，改變收集器材料與溶液的成分可以控制纖維的形貌，使其能呈現光滑竹節狀或者粗糙實心的纖維產生，而改變收集器的材料可以得到較規則有序排列。以FE-SEM和TEM觀察纖維表面形貌與直徑，鑑定是否為連續纖維且達到奈米的尺寸，以AFM掃描單根奈米陶瓷纖維，探討其表面形貌，將製備之試片使用XRD針對其結晶性質分析，再利用PL光譜儀來對其光學性質之探討與研究。如此一來可以建立靜電紡陶瓷奈米纖維的顯微結構與吸光、結晶性質的關聯性。此外本實驗成功建立一套核心技術，能夠藉由控制配方的調配形成竹節光滑或者實心粗糙的纖維形貌，在高溫熱處理後能連續製備大面積的纖維不織布。

This study is the use of nano-ceramic fibers prepared by electrospinning. In the preparation of the precursor solution, adding an appropriate amount of PVP and solution made the appropriate to concentration ,and successfully prepared a large number of nano-fibers. And after heat treatment, fiber unbreakable. Using the following instrument AFM, FE-SEM, HRTEM, XRD analysis for the same sample. Part I: Prepared by using different heat treatment temperature to ceramic nano fluorescent fibers, found that the higher temperature heat treatment the ceramic nanofiber crystalline was bigger and more closely spaced. Part II: we focus on the control the electrospinning fiber by changing collect and the ratio of the solution modulation to control morphology of the fibers, it can have a smooth and hollow or rough and solid fiber production, to change the way the collector can be more regular and orderly arrangement. Using FE-SEM, TEM explore its morphology and fiber diameter, identified whether and to achieve nanoscale continuous fiber. AFM scanning single nano-ceramic fibers,explore the nature of the surface morphology. The sample will be prepared for its crystalline properties were characterized by XRD do explore. Finally we explored and examined optical properties by use PL spectrometer. This way can create electrospinning nano-fiber molecular structure and absorption, crystalline nature of the association and to establish correlation analysis techniques to explore the changing nature of its physical, optical, and crystal structure. In addition, this experiment successfully established a set of core technologies, and can be control deployed to formation fibers with smooth and hollow or rough and solid, produce a large area fibers after high temperature treatment.
